|
The elements for AB are combined visual-spectroscopic. |
Hei1963c |
|
A secondary radial velocity variation with a period of about 70d |
|
|
was suspected by Underhill (Pub. DAO Victoria 12, 161, 1963) |
Fin1970b |
|
See Baize & Petit (1989) catalog of doubles with variable component. |

| STF1273 |
C is SB1, P = 9.905 d. |
|
|
AB,C triple solution ((AB)-C in HIP). |
Sod1999 |
|
Star D is in slow direct motion, hence quintuple. |
